The elastic claw 24 is matched with the clamping protrusion 151 arranged on the inner wall of the shell 1, when the mounting base 2 is mounted in the accommodating cavity of the shell 1, the elastic supporting portion 241 of the elastic claw 24 firstly contacts with the clamping protrusion 151, the elastic supporting portion 241 is gradually compressed and deformed along with the continuous pushing of the mounting base 2 until a gap at the joint of the elastic supporting portion 241 and the clamping portion 242 penetrates through the clamping protrusion 151, the elastic supporting portion 241 rebounds, the clamping protrusion 151 is clamped with the gap, meanwhile, the first circuit board 8 is just mounted in the first clamping plate groove 111 and the second clamping plate groove 121, one side of the body of the mounting base 2 is abutted against the first clamping plate protrusion 11 or the supporting protrusion 13, and the mounting firmness of the mounting base 2 can be effectively guaranteed. When the mounting seat 2 needs to be detached, only the pressing portion 243 of the elastic claw 24 needs to be pressed, the elastic supporting portion 241 deforms, the gap is separated from the clamping protrusion 151, and therefore the mounting seat 2 can be smoothly and conveniently taken out from the accommodating cavity of the shell 1.

Of course, it should be understood that the above-mentioned shape of the resilient latch 24 is merely preferred, and that the resilient latch 24 may have other shapes in specific implementations. For example, the elastic claw 24 has a T-shape, and the engaging portion and the pressing portion are connected to the main body 20 through the elastic support portions, respectively. The engaging end of the engaging portion faces the side of the main body 20 where the plate fixing structure 22 is disposed, and the engaging end faces the side of the mounting through hole 21 where the hook is disposed. The free end of the pressing portion faces the side of the body 20 where the ring-shaped structure 23 is provided. When the mounting base 2 is mounted in the accommodating cavity of the housing 1, the hook of the elastic claw 24 engaging portion contacts with the hook projection 151 first, and along with the continuous pushing of the mounting base 2, the elastic claw 24 engaging portion deforms until the hook passes through the hook projection 151, the elastic claw 24 engaging portion rebounds, the hook projection 151 engages with the hook, and at this time, the first circuit board 8 is just mounted in the first board groove 111 and the second board groove 121, and one side of the body of the mounting base 2 abuts against the first board projection 11 or the supporting projection 13, so that the mounting firmness of the mounting base 2 can be effectively guaranteed. When needs are dismantled during mount pad 2, only need press the splenium of pressing of elasticity jack catch 24, the elastic support portion takes place deformation, towards pressing direction one side bending, the perk of block portion of elasticity jack catch 24, the pothook with the protruding 151 separation of card, so can be smoothly and convenient will mount pad 2 is followed the holding intracavity of shell 1 takes out. The elastic claw 24 can also be used in cooperation with the clamping lug, that is, the clamping hook of the elastic claw 24 is inserted into the clamping hole of the clamping lug and clamped with the clamping lug, and the disassembly and assembly are far from the same point, which is not described herein.

In addition, when the signal transmitter adopts two kinds of different shapes of elastic claw 24, the corresponding buckle structure 15 that selects to set up in the shell 1 corresponds with it can also play the foolproof effect to a certain extent, prevents that the mount pad 2 from installing orientation mistake when in the shell 1.
